Application June 12, 1958, Serial No. 741,578 2 Claims. (Cl. 182-407) This invention relates to new and useful improvements in shoe scrapers and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character which is adapted to be readily mounted for convenient use on a conventional ladder whereby a person, about to climb the ladder, may remove mud, snow, etc., from the shoes to avoid slipping.

Another important object of the invention is to provide a shoe scraper of the aforementioned character comprising novel means for firmly securing the device on one of the usual ladder rungs, preferably the bottom or first rung, without the necessity of weakening or structurally altering the same.

Still another important object of the present invention is to provide a shoe scraper of the character described which will interfere in no way with the use of the ladder on which it is mounted.

Other objects of the invention are to provide a shoe scraper of the character set forth which will be comparatively simple in construction, strong, durable, compact and which may be manufactured at low cost.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a view in front elevation, showing a shoe scraper constructed in accordance with the present invention mounted for use on a ladder;

Figure 2 is a fragmentary view in front elevation with a portion of the ladder rail broken away in section to show the means for anchoring the scraper blade thereto; and

Figure 3 is an enlarged view in transverse section, taken substantially on the line 33 of Figure 1.

Referring now to the drawing in detail, it will be seen that reference character 4 designates generally the lower portion of a conventional straight ladder of suitable wood. The ladder 4 includes the usual rails 5 and rungs 6 extending between said rails.

The embodiment of the present invention which has been illustrated comprises an elongated blade 7 of suitable metal which is adapted to be mounted longitudinally on one end portion of the bottom or first rung 6 of the ladder 4. Toward this end, the blade 7 has mounted thereon at longitudinally spaced points a pair of clamps 8 for engagement with the rung 6.

Each clamp 8 includes a pair of substantially semi-circular, duplicate jaws 9 which terminate in flat end portions 10 and 11. The end portions 10 of the jaws 9 are ice pivotally secured at 12 to the blade 7 on opposite sides thereof. The jaws 9 receive the ladder rung 6 therebetween and said jaws are clamped on said rung through the medium of a bolt 13 mounted in openings provided therefor in the free end portions 11 of said jaws and having threaded thereon a nut 14.

As shown to advantage in Figure 1 of the drawing, the blade 7 comprises a rounded inner end 15. The outer end 16 of the blade 7 is square cut for abutting engagement with the adjacent rail 5 of the ladder 4. Projecting longitudinally from the end 16 of the blade 7 is a prong or tooth 17 which is adapted to be driven into the adjacent rail 5 for positively anchoring said blade thereto. The blade 7 still further comprises a scraping edge 18 extending across the top and around the curved end 15 of said blade.

It is thought that the use of the scraper will be readily apparent from a consideration of the foregoing. Briefly, the blade 7 is positioned longitudinally on the bottom or first rung 6 of the ladder 4 and the clamps 8 are engaged loosely with said rung. The device is installed on the left hand end portion of the rung 6. Thus, the major portion of the rung is left clear or unobstructed to be used in the usual manner. The tooth or prong 17 is driven into the adjacent ladder rail 5, after which the clamps 8 are tightened on the rung 6, thus firmly securing the device in position. The tooth or prong 17 positively secures the blade 7 against turning on the rung.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. The combination with a ladder of the type comprising a pair of rails and a rung of circular transverse section extending therebetween, of a shoe scraper including a blade of a length less than that of the rung and mounted longitudinally on one end portion thereof, with one end in abutting engagement with one of the rails, clamps on the blade engaged with the rung for frictionally and rotatably adjustably securing said blade thereon, and a tooth on said one end of the blade embedded in said one rail for anchoring said blade thereto and positively securing said blade in rotatably adjusted position on the rung.

2. The combination with a straight ladder including a rail and a circular rung mounted thereon, of a shoe scraper comprising an elongated blade paralleling the rung, clamps frictionally securing the blade on the rung, and a driven tooth projecting from one end of the blade in the longitudinal plane thereof and embedded in the rail for positively anchoring said blade against rotation on the rung.
